คู่มือการใช้งานวาล์วโซลินอยด์ Danfoss EVR 3 (รุ่น 032F1204)

1. บทนำ

This instruction manual provides essential information for the safe and efficient installation, operation, and maintenance of the Danfoss EVR 3 Solenoid Valve, model 032F1204. Please read this manual thoroughly before attempting any procedures to ensure proper function and to prevent potential hazards.

2. สินค้าหมดview

The Danfoss EVR 3 is a normally closed (NC) solenoid valve designed for various industrial and refrigeration applications. It features 3/8 inch ODF (Outside Diameter Flared) connections, ensuring a secure and leak-tight fit. This valve is engineered for reliability and precise control of fluid flow.

3. ข้อมูลด้านความปลอดภัย

• Always disconnect power before installing, servicing, or removing the solenoid valve.
• Ensure the system pressure is relieved before working on the valve.
• ควรสวมใส่อุปกรณ์ป้องกันส่วนบุคคล (PPE) ที่เหมาะสม เช่น แว่นตานิรภัยและถุงมือ
• การติดตั้งและบำรุงรักษาควรดำเนินการโดยบุคลากรที่มีคุณสมบัติเท่านั้น
• Verify that the valve's specifications (pressure, temperature, fluid compatibility) match the application requirements.
• Avoid exposing the valve to excessive mechanical stress or vibration.

4. การติดตั้ง

4.1 การตรวจสอบก่อนการติดตั้ง

• Inspect the valve for any signs of damage during shipping.
• Confirm that the model number (032F1204) and specifications match your order and application.
• Ensure all necessary tools and fittings are available.

4.2 Mounting and Connection

1. Mount the valve in a position that allows for easy access for maintenance and inspection. The valve can be installed in any position, but it is recommended to install with the coil upwards to prevent accumulation of debris.
2. Ensure the flow direction arrow on the valve body aligns with the system's fluid flow.
3. Connect the 3/8 inch ODF pipes to the valve's inlet and outlet ports. Use appropriate flaring tools and techniques to ensure a leak-free connection.
4. Tighten connections to the manufacturer's recommended torque specifications to prevent leaks without over-stressing the valve body.

4.3 การเชื่อมต่อไฟฟ้า

• ตรวจสอบแหล่งจ่ายไฟ voltage and frequency match the specifications of the solenoid coil.
• Connect the solenoid coil to the appropriate electrical circuit. Follow local electrical codes and safety standards.
• Secure all electrical connections to prevent accidental disconnection or short circuits.

5. การดำเนินการ

The Danfoss EVR 3 (032F1204) is a normally closed (NC) solenoid valve. This means that when the solenoid coil is de-energized (no power), the valve remains closed, preventing fluid flow. When the solenoid coil is energized (power applied), the valve opens, allowing fluid to pass through.

• การจ่ายพลังงานให้คอยล์: Applying the specified voltage to the solenoid coil will open the valve.
• การตัดพลังงานของคอยล์: Removing power from the solenoid coil will close the valve.

Monitor system pressure and flow rates after initial operation to ensure proper function and detect any anomalies.

6. การบำรุงรักษา

6.1 การตรวจสอบตามปกติ

• Periodically check for external leaks around the connections and valve body.
• Inspect the solenoid coil for any signs of overheating, damage, or loose connections.
• ฟังเสียงที่ผิดปกติในระหว่างการทำงาน ซึ่งอาจบ่งบอกถึงปัญหาภายใน

6.2 การทำความสะอาด

• Keep the exterior of the valve clean and free from dust, dirt, and corrosive substances.
• If internal cleaning is required, consult a qualified technician or Danfoss service representative. Disassembly by untrained personnel can void warranty and cause damage.

6.3 Coil Replacement

If the solenoid coil fails, it can typically be replaced without removing the entire valve from the system. Ensure the power is disconnected before attempting coil replacement. Refer to the specific coil's instructions for detailed replacement procedures.
